Hi there,

My friend and I received help with regards to vacuum bagging from Paul at Easy Composites yesterday and I can't recommend him enough, valuable advice and very helpful!

It came time to de-bagging today and our finished product hasn't turned out as we expected. I've attached some pictures, what could we have done wrong?

We used some temporary adhesive so that may be the murkiness of the top-most layer, but along the edges of the part there seems to be just lines of glue. Could this indicate that the cloth wasn't properly pressed into all the crevices at the time of bagging, too much resin, wrong curing temperature? 

Last night when we got back home it looked like the bag was still under vacuum. We placed an electric blanket underneath and then covered the part with the breather cloth. I think it may have been better to use a duvet as it didn't seem too warm when I went in the garage this morning.

Any help would be appreciated!
P.S. we bagged at 5pm yesterday and de-bagged today at 19:00 having used the Fast hardener.

Is this wet-lay vac bagging or infusion? It looks like a wet-lay result. In which case, it's really just a lot of bridging. Sorting out the bridging will give a much better result.

If its infusion,  Mat is bang on.

It's infusion so it's possible that there was bridging but we had Paul helping us so no clue honestly. Trial and error I suppose

Sure Paul helped you out in an excellent way but there is still a lot skill needed. There is still a big margin or error between verbal information (or watching tutorials online) and doing it before getting the good parts...you have to see it like a trial and error where you can eliminate problems each time you make a new part
